I bought this last week and couldn't be happier! I have the XB40 and this speaker is basically a larger version so I had to get it. The sound quality is great, the volume is as well. The bass is outstanding! Perfect for a party with the flashy, or calm lights that YOU can set yourself.

I bought this thing last week so I can't speak towards its durability (yet). I can. Tell you that it is solidly constructed, I had no issue connecting it to my iPhone via Bluetooth and the sound is outstanding. Would I use it in a garage band? No. Would I use it in my house or at a party? Oh yeah... looking forward to it. I may even give it a shot in the back of my jeep this summer, we'll see.

This speaker is so loud and so clear! The bass is freaking awesome and I love the light show! It is possible to find this speaker at lower prices but it is worth the price that Sony is selling it for! This speaker has to be plugged in and that is the only drawback to this wonderful speaker.

I loved my first speaker so much, that I went back and bought another speaker. Now whenever I host get togethers at my home, theirs never a dull moment. Sound quality is equal to a high end club dj speaker system. Neighbors are not so happy with me now, but what can I say, I like loud music.
